DRILLING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 554,940, dated February18, 1896. Application filed May 6,1895. s a NO- 548,320. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT C. LIEBEN- DORFER, a citizen of the UnitedStates, residing at Ottawa, in the county of La Salle and State ofIllinois, have invented certain new and useful Improvements inDrilling-Machines; and'I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in drilling-machines, and has moreparticular relation to machines for drilling wells.

It consists of certain novel constructions, combinations, andarrangements of parts, all of which will be hereinafter moreparticularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure1 represents a side elevation of a machine embodying my invention. Fig.2 represents a transverse vertical section through the same. Fig. 3represents a detail side elevation, partly in section, of thespring-controllin g devices. Fig. 4 represents a horizontal sectionthrough the same, and Fig. 5 represents a detail section of the cam andmountings for operating the frictionwheel.

A in the drawings represents the truck, of any suitable construction, bywhich the machine may be moved to the different fields of operation. Bis the vertical frame mounted on this truck, 0 the hollowoperating-drill, and D the spring devices for controlling the operationof said drill.

The frame B is mounted on the forward end of the truck, and consists oftwo vertically and forwardly inclined standards I), attached to the sidebeams of the truck and held firmly in position by the inclined bracesI), also attached to the respective side beams of the machine. Awalking-beam b is pivotally mounted between the standards I) and isprovided at its rear end with a pitman b pivotally pendent therefrom.The lower end of said pitman is mounted upon a crank-pin b of acrank-disk 19 This disk is mounted on the inner end of the mainoperating-shaft 19 which is mounted'transversely of the truck and underthe rear end of the walking-beam by j ournal-boxes b attached to thelongitudinal beams of the truck. This shaft carries a belt-Wheel e, afly-wheel e, and a friction-wheel 6 the latter being composed of asuitable hub or wheel covered about its periphery with leather or somelike frictional material.

The spring devices D for controlling the action of the drill consist ofan inverted-yokeshaped frame 61, having lateral lugs d, by which it isattached to the transverse beams of the frame of the truck. The verticalarms of this yoke are provided upon their inner faces with verticalguides (1 upon which the grooved head (1 is adapted to slide and beguided. This head, as shown in Figs. 3 and 4, is provided upon its uppersurface with three circular spring-retaining projections (1 the middleone of which is apertured to permit the end of a connecting-rod d to bepassed therethrough and secured by a suitable locking-nut.

The under side of the horizontal portion of the yoke is provided withthree tubular pendent projections d adapted to support the upper ends ofthe spiral springs (1 which are interposed between the head d and saidhorizontal portion of the yoke. The rod (1 passes through the middle oneof said projections d and is formed with an eye d at its'upper end. Arod (1 having a turnbuckle c1 connects said rod (1 and the pitman 12 Anauxiliary shaft F is mounted on the frame A in the rear of, the shaft band is provided with a reel or drum f, a friction-wheel f adapted toengage the wheel 6 and a cam-disk f the latter being shown in Fig. 5with the shaft passing loosely through it to one side of its truecenter. This cam is provided with an operating-arm f which passesthrough a slot f cut in the top half of the divided bearingbox f mountedon the truck-beam and in which the cam is set. The arm f is connected toan operating-lever f pivoted at the front of the machine by aconnecting-rod f", said lever being provided with rack and pawl securingdevices f for holding it in the desired adjusted position.

It will be seen from the foregoing that when it is desired to rotate thedrum f the lever f is pushed forward and the shaft F thus forced forwardas the cam f revolves. This action will bring the wheel f in contactwith the wheel 6 and thus the shaft F will be revolved and wind the ropef upon the drum, the said rope passing over apulley at the top of theframe B and being provided with a suitable hook f.

The drill C is provided with a suitable hollow drill-rod 0 having twotwisting-handles c rigid therewith and is screw-threaded at its upperend to work in the temper-screwc the latter being attached at its upperend to the forward end of the walking-beam bya swiveljoint, and a clamp0 being provided at the lower end of the temper-screw to bind the samein any desired adjusted position 011 the rod 0. Apertures c" are formedin the lower end of the drill-rod, so that the water, sand, Also. ,canpass upward through said rod. WVhen it is desired to rotate the rod 0 tomove it downward as the drillingprogresses, the same is accomplished byturning the handles 0.

\Vhen it is desired to raise or lower the drill from or into the well toaffix a new point or the like, the temper-screw c is uncoupled from thewalking-beam and the hook f S hooked in the same. The drum f is thenretated, as before described, and the rope f wound thereon, which willelevate the drill. If desired, when raising the drill the pitman Z) androd d" may be uncoupled from the crank-disk and the rod d respectively,so that the spring device D will not operate.

By means of the spring device D, I am enabled to produce a sharp quickstroke of the drill, which is more like a rebounding tap than a steadydownstroke as the springs are compressedas the drill descends, thusslightly decreasing the force of the stroke and causing the drill tostrike with a quick jerking action, which I find produces the bestresults.

The drillings pass up through the rod 0 and discharge through thehandles 0'.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, isi 1. In a drilling-machine, the combinationof a portable truck carrying a suitable frame,

a walking-beam mounted on said frame, a

drill detaehabl y mounted on the outer end of said beam, mechanism forreciprocating said beam, spring devices for restraining the movements ofsaid beam mounted on the frame and comprising a yoke having internalvertical guides and pendent cylindrical spring-s11pporting projectionsone of which serves as a guide for a connecting-rod, a head sliding onsaid guides, a bar passing through one of said projections andconnecting said head with the walking-beam, and a plurality ofcoil-springs mounted on said projections and engaging said head,substantially as described.

2. In a drilling-machine, the combination of a portable truck carrying asuitable frame, a walking-beam mounted on said frame, a drill detachablymounted on the outer end of said beam, mechanism for reciprocating saidbeam, spring devices for restraining the movements of said beam mounted011 the frame and comprising a yoke having internal vertical guides andpendent cylindrical spring-supporting projections one of which serves asa guide for a conneeting-rod, ahead sliding on said guides, a barpassing through one of said projections and connecting said head withthe walking-beam, and a plurality of coil-springs mounted on saidprojections and engaging said head, a turnbuckle for increasing ordecreasing the length of said bar, whereby the tension of the springs isdecreased or increased at will and a tackle and winding-drum for raisingthe drill independently of the walking-beam, substantially as described.

3. In a drilling-machine, the combination of a portable truck carrying asuitable frame, a walking-beam mounted on said frame, a drill detachablymounted 011 the outer end of said beam, mechanism for reciprocating saidbeam, spring devices for restraining the movements of said beam mountedon the frame and comprising a yoke having internal vertical guides andpendent cylindrical spring-supporting projections one of which serves asa guide for a connecting-rod, a head sliding on said guides, a barpassing through one of said projections and connecting said head withthe walking-beam, and a plurality of coil-springs mounted on saidprojections and engaging said head, a winding-drum and tackle and meansfor moving said drum into or out of engagement with the moving parts ofthe machine at will, substantially as described.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

ALBERT C. LIEBENDORFIER.
